Abstract

This article is insisted to studying the problems on sharing value for the non-linear differential polynomial with its shift and q-difference. The results in this paper improve and generalize the recent results due to S. C. Kumar, S. Rajeshwari, T. Bhuvaneshwari [J. Math. Comput. Sci., 12(2022), 1-16.]
